Seems like web::Json can't deserilize json with nested keys as payload inside requests into rust structs

Your issue may already be reported! Please search on the Actix Web issue tracker before creating one.

Expected Behavior

Here is a json

{
    "name": "foo",
    "bar": {
            "foo": "bar"
     }
}

This is the defination of the api

#[derive(Serialize, Deserialize, Debug)]
struct Foobar{
    foo: String
}

#[derive(Serialize, Deserialize, Debug)]
struct Foo {
    name: String,
    bar: Foobar
}

use actix_web::{post, web::Json, Error, HttpResponse};
#[post("/test")]
async fn test(req: Json<Foo>) -> Result<HttpResponse, Error> {
    println!("{:?}", req);
    Ok(HttpResponse::Ok().body("hi"))
}

web::Json can't deserilize json with nested keys as payload inside requests into rust structs, and resolve the request as 400 (Bad request)

Current Behavior

Unable to deal with nested keys of json file
